Smart Functional Hydrogels: Emerging Platforms for Thermal and Electrochemical Energy Harvesting and Conversion Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogel exhibits versatile functions, including efficient thermogalvanic conversion under a temperature difference, and acting as a cooling layer/forming a thermally conductive nanoactive composite for thermovoltaic conversion. Additionally, its self‐healing and self‐powered flexibility play a key role in energy storage systems. The growing demand

An Excellent Deep‐Ultraviolet Nonlinear Optical Crystal Realized via a Functional Group Based on a Two‐in‐One Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A “two‐in‐one” design strategy integrating guanidinium and carboxyl functional groups was developed to overcome the intrinsic trade‐off among SHG response, ultraviolet cutoff edge, and birefringence in DUV NLO crystals. Benefiting from non‐π‐conjugated electronic isolation, Zn‐GPA(II) simultaneously achieves a strong SHG response (2.1 × KH2PO4), an ...

A Robust Densification Strategy Toward Ultrahigh Energy Density in All‐Organic Dielectric Polymer Films

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable densification strategy is proposed by incorporating sucrose into a fluoropolymer matrix to build a robust hydrogen‐bond crosslinking network. The intermolecular interactions effectively facilitate polar phase transformation and reduce free volume fraction.

A Numerical Investigation of the Effects of Piston Bowl Geometry and Spray Angle on Combustion, Performance and Emission of a Diesel Engine

open access: yesEnergy Science &Engineering, EarlyView.
A piston bowl's design and spray angle improve air‐fuel mixing, resulting in more complete combustion and higher efficiency. Ansys Forte 2023 R1 a CFD software was used to analyze the effects of five combustion chamber geometries of cylinder, modified re‐entrant, re‐entrant, double‐stepped, and stepped on engine performance, combustion, and emission ...

Catalytic Pyrolysis of Torrefied Municipal Solid Waste Using Local Iron for Improved Bio‐Oil Yield and Energy Efficiency

open access: yesEnergy Science &Engineering, EarlyView.
Catalytic Pyrolysis of Torrefied Municipal Solid Waste to sustainable bio‐oil. ABSTRACT South Africa faces growing municipal solid waste (MSW) accumulation and energy insecurity due to fossil fuel dependence. Torrefaction improves MSW for waste‐to‐energy use, while conventional pyrolysis produces low‐quality oxygen‐rich bio‐oil.
